V BESILIENT AUTOMOBILE-WHEEL.

Application filed March 13, 1913, Serial No. 754,

To all whom it may concern Be itlmown that I, WILLIAM A. Dawson,residing at Delta, in the county of Delta and State of Colorado, haveinvented a new and useful Resilient Automobile-Wheel; and Idohereby-declare the following to be a full, clear, and exactdescription of the invention, such skilled in the art to which itappertains to make and use the same. r

f This invention relates to a new and useful resilient automobile wheel,and one in which the resiliency is interposed between the spokes and theinner skein or sleeve of the hub of the wheel.

As one of the objects of the invention, there is provided an innerrubber disk having a series of sockets to receive the solid rubber ballsof the inner ends of the rod spokes, thus allowing the rod spokes toyield; An object of the invention is to construct the rim of the wheelof a plurality of sections, joined together in sequence by loose slipjoints as shown in the drawings. Each section of the tireis carried by arod spoke.

Another object of the invention is the provision of ametallic bandsurrounding the rubber plate, between which and the shoulders on the rodspokes, springs are interposed, to further insure resiliency.

,One of the features of the invention is the provision of tubularmembers or sheaths surrounding the springs, and into which two partmembers having packing and ball bearings are threaded; said two partmembers with the packing therein, not only acting to exclude the dustand the like, but also owing to the lubrication in the packing and theball bearings constituting means to allow the spokes to reciprocateeasily, as the sections of the tire come in contact with the ground.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and claimed.

In the drawings :-Figure 1 is a vertical sectional view through theimproved wheel construction in accordance with the invention. Fig. 2 isa sectional view on line 22 of Fig. 1. Fig. 3 is a side elevation of theimproved wheel. Fig. 1 is a detail view of one of the two part members.

Referring more particularly to the draw- Specification of LettersPatent.

ings, 1 designates the inner member of the hub portion of the wheel.This inner memher is provided with a sleeve or skein 2, which passesthrough a plate 3, the outer portion of which is supplied with a seriesof tubular members or sheaths 4:. The plate 8 is recessed on one sidethereof to receive the rubber disk 5, betweenwhich and the inner end ofthe tubular members'or sheaths 4: an annular metal band 6 is provided.The sleeve or skein 2 also passes through the rubber disk 5, and isthreaded into the other member '7 of the hub. The rubber disk 5 isprovided with aseries of sockets 8, to receive the rubber balls fixed tothe inner ends of the rod spokes 9 of the wheel. The rod' terposed. Thecoil springs 11 are located in the tubular members 'or sheaths 1.

In order to exclude dust and the like from the tubular members orsheaths, and to insure easy movements for thespokes 9 members 12 arethreaded at 13 into the tubular members or sheaths. These members 12consist of two parts 1 1 and 15, threadedtogether asat 16. The parts 11are threaded into the tubular members or sheaths 4. Lo

cated upon the interior of the members 12.

and surrounding the rod spokes 9 are clamp rings 17 These clamp ringsdivide the members 12 into two compartments 18 and 19. In thecompartments 18 ball bearings 20 are mounted, while in the compartments19 packing 21 saturated with lubricating oil is arranged thus acting toexclude all dust or dirt and water from entering the tubular members orsheaths. The ball bearings 20 insure easy movements of the rod spokes 9.The outer ends of the rod spokes 9 are threaded at 22 into the sections23 of the rim 24; of the wheel. end is provided with a pocket or recess25 to receive the reduced extension plate 26, of one end of the adjacentsection. V In this manner loose joints are afiorded between thesections. The outer faces of the sections are provided with the wheelfrom slipping. 7

It is to be ascertained from the foregoing that there has been devised anew and useful, simple and practical form of resilient auto- Eachsection 23 at one Patented Mar. 9, 1915.
